FIGHTING METHOD With impulse noise BASED ON THEIR LOCALIZATION OF MIN-MAX thresholds in adaptive system radio reception

摘要

A method for controlling transients (SP) on the basis of their localization with min-max threshold in adaptive systems receiving radio signals, comprising the steps, in order to eliminate the influence of PI on adaptive radio reception system using the compensation path detuned from the frequency of the received signal, the amplitude limiter , the interval signal replacement procedure SP noise (auxiliary signals), linear, median filtering, characterized in that for the localization of SP formed envelope signal observation pa Byway it to L / N blocks (L - length of the observation of the original signal, N - block size L when multiple N), selected maximum value of the envelope at each block and generating from them a first sequence; is then obtained from the first sequence of blocks of length M are formed (at L / N multiple of M) are selected in each block the minimum value of them and form a second sequence; more cubic interpolation curve constructed, where the / interpolation of nodal points located increments M · N, a second sequence of values ​​is used, and as the boundary nodal points of the first and last values ​​of the second sequence; the resulting curve used as useful signal and noise envelope estimation for calculating the min-max threshold that takes into account the probability of the error detection SP; calculated min-max threshold are used to determine slots of action (indexes starting positions, lengths) in the original signal SP observation; when processing the observation signal in the range of action of each of the stop SP is performed and fixed state calc algorithm
